ABSTRACT
Generally buffalos (Bubalus bubalis) are widespread in tropical and subtropical areas, warm and humid climates. In the world, there are 182 million buffalo heads, and 95% of total population is in Asia. In Europe, there are 459 000 buffalo heads (0.25% on world population), of which in Italy are 370 000 buffalos. In the last period the trend has been declining, especially in the Balkan countries (Romania, Bulgaria, Macedonia, Greece, Albania and Serbia). In Romania, the last 30 years the number has dropped from 228 000 to 22 400 buffalo heads. This decrease in the number of buffalos in Romania was caused by the unfavorable agricultural policy for buffalo species. This study was conducted in Transylvania (central Romania)) and the Romanian Plain, along the Danube River. The working method was to analyze statistical data on 100 years, the chemical analyzes performing with Ecomilk device and performing body measurements. Data were processed by mathematical methods, and the results were compared to the literature. From the results it was found that in Romania there are ecotypes of river buffalos, adapted ecological zone. Each population is characterized by adaptation to a particular habitat, specific resistance to certain diseases. We analyzed the reproductive indicators and we observed that the population from southern Romania, in the Danube valley is precocious (the age of first mating is 31.33 days, and the age of first calving is 41.82 days). Buffaloes population from Transylvania is belated (the age of first mating is 38.16 days and the first calving age 48 days). The calving interval was also variable, ranging from 478.06 days in buffaloes population from Transylvania and 509.93 days in buffaloes from Danube Valley (p<0.01). In both populations analyzed the birth rate ranged from 87.24 to 91.41% and the fecundity rate from 73.32 to 75%. The body development of buffaloes in Romania is variable depending on the ecological area. Thus, in the South of Romania the animals have the body development smaller (the size of withers 132.17 cm, the oblique length of trunk 138.04 cm, the thoracic perimeter 198. 14 cm, the body weight 622.30 kg) in Transylvania the body development of buffaloes is larger (the size of withers 136 cm, the oblique length of trunk 141 cm, the thoracic perimeter 193.14 cm, the body weight 638 kg) (p <0.01). Regarding of milk production, buffaloes analyzed from Romania realized 1669.03 kg milk in 274.74 days of lactation with 7.65% fat and 4.30% protein. This species is suitable for organic farms, obtaining organic food with high nutritional value.
